In a study conducted at the University of Twente, Technion-Israel Institute of Technology and the Open University of Israel, researchers have developed a novel approach to address the environmental challenges posed by perchlorate salts, which have been identified as persistent pollutants with potential impacts on human health.
The researchers published (opens in a new tab) their findings in an article titled “Selective Perchlorate Sensing Using Electrochemical Impedance Spectroscopy with Self-Assembled Monolayers of semiaza-Bambusurils,” in the journal Chemistry—A European Journal.
Perchlorate salts are a type of anion—slightly negatively charged molecules—which have raised concerns due to their ability to interfere with the proper functioning of the thyroid gland, leading to hypothyroidism. These molecules are highly soluble in water, but difficult to detect. Therefore the researchers worked on developing a new material that can bind these perchlorate salts and send out a signal when they are detected.
